## registry:style

### Custom style that extends shadcn/ui

The following registry item is a custom style that extends shadcn/ui. On `npx shadcn init`, it will:

- Install `@tabler/icons-react` as a dependency.
- Add the `login-01` block and `calendar` component to the project.
- Add the `editor` from a remote registry.
- Set the `font-sans` variable to `Inter, sans-serif`.
- Install a `brand` color in light and dark mode.

```json title="example-style.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "example-style",
  "type": "registry:style",
  "dependencies": ["@tabler/icons-react"],
  "registryDependencies": [
    "login-01",
    "calendar",
    "https://example.com/r/editor.json"
  ],
  "cssVars": {
    "theme": {
      "font-sans": "Inter, sans-serif"
    },
    "light": {
      "brand": "20 14.3% 4.1%"
    },
    "dark": {
      "brand": "20 14.3% 4.1%"
    }
  }
}
```

### Custom style from scratch

The following registry item is a custom style that doesn't extend shadcn/ui. See the `extends: none` field.

It can be used to create a new style from scratch i.e custom components, css vars, dependencies, etc.

On `npx shadcn add`, the following will:

- Install `tailwind-merge` and `clsx` as dependencies.
- Add the `utils` registry item from the shadcn/ui registry.
- Add the `button`, `input`, `label`, and `select` components from a remote registry.
- Install new css vars: `main`, `bg`, `border`, `text`, `ring`.

```json title="example-style.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "extends": "none",
  "name": "new-style",
  "type": "registry:style",
  "dependencies": ["tailwind-merge", "clsx"],
  "registryDependencies": [
    "utils",
    "https://example.com/r/button.json",
    "https://example.com/r/input.json",
    "https://example.com/r/label.json",
    "https://example.com/r/select.json"
  ],
  "cssVars": {
    "theme": {
      "font-sans": "Inter, sans-serif",
    }
    "light": {
      "main": "#88aaee",
      "bg": "#dfe5f2",
      "border": "#000",
      "text": "#000",
      "ring": "#000",
    },
    "dark": {
      "main": "#88aaee",
      "bg": "#272933",
      "border": "#000",
      "text": "#e6e6e6",
      "ring": "#fff",
    }
  }
}
```

## registry:theme

        "padding": "var(--spacing-6)",
        "box-shadow": "var(--shadow-xl)"
      }
    }
  }
}
```

## Add custom utilities

```json title="example-component.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "custom-component",
  "type": "registry:component",
  "css": {
    "@utility content-auto": {
      "content-visibility": "auto"
    }
  }
}
```

  "type": "registry:component",
  "css": {
    "@utility scrollbar-hidden": {
      "scrollbar-hidden": {
        "&::-webkit-scrollbar": {
          "display": "none"
        }
      }
    }
  }
}
```

### Functional utilities

```json title="example-functional.json" showLineNumbers

  "css": {
    "@utility tab-*": {
      "tab-size": "var(--tab-size-*)"
    }
  }
}
```

## Add CSS imports

Use `@import` to add CSS imports to your registry item. The imports will be placed at the top of the CSS file.

### Basic import

```json title="example-import.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "custom-import",
  "type": "registry:component",
  "css": {
    "@import \"tailwindcss\"": {},
    "@import \"./styles/base.css\"": {}
  }
}
```

### Import with url() syntax

```json title="example-url-import.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "font-import",
  "type": "registry:item",
  "css": {
    "@import url(\"https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600&display=swap\")": {},
    "@import url('./local-styles.css')": {}
  }
}
```

### Import with media queries

```json title="example-media-import.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "responsive-import",
  "type": "registry:item",
  "css": {
    "@import \"print-styles.css\" print": {},
    "@import url(\"mobile.css\") screen and (max-width: 768px)": {}
  }
}
```

## Add custom plugins

Use `@plugin` to add Tailwind plugins to your registry item. Plugins will be automatically placed after imports and before other content.

**Important:** When using plugins from npm packages, you must also add them to the `dependencies` array.

### Basic plugin usage

```json title="example-plugin.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "custom-plugin",
  "type": "registry:item",
  "css": {
    "@plugin \"@tailwindcss/typography\"": {},
    "@plugin \"foo\"": {}
  }
}
```

### Plugin with npm dependency

When using plugins from npm packages like `@tailwindcss/typography`, include them in the dependencies.

```json title="example-typography.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "typography-component",
  "type": "registry:item",
  "dependencies": ["@tailwindcss/typography"],
  "css": {
    "@plugin \"@tailwindcss/typography\"": {},
    "@layer components": {
      ".prose": {
        "max-width": "65ch"
      }
    }
  }
}
```

### Scoped and file-based plugins

```json title="example-scoped-plugin.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "scoped-plugins",
  "type": "registry:component",
  "css": {
    "@plugin \"@headlessui/tailwindcss\"": {},
    "@plugin \"tailwindcss/plugin\"": {},
    "@plugin \"./custom-plugin.js\"": {}
  }
}
```

### Multiple plugins with automatic ordering

When you add multiple plugins, they are automatically grouped together and deduplicated.

```json title="example-multiple-plugins.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "multiple-plugins",
  "type": "registry:item",
  "dependencies": [
    "@tailwindcss/typography",
    "@tailwindcss/forms",
    "tw-animate-css"
  ],
  "css": {
    "@plugin \"@tailwindcss/typography\"": {},
    "@plugin \"@tailwindcss/forms\"": {},
    "@plugin \"tw-animate-css\"": {}
  }
}
```

## Combined imports and plugins

When using both `@import` and `@plugin` directives, imports are placed first, followed by plugins, then other CSS content.

```json title="example-combined.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "combined-example",
  "type": "registry:item",
  "dependencies": ["@tailwindcss/typography", "tw-animate-css"],
  "css": {
    "@import \"tailwindcss\"": {},
    "@import url(\"https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600&display=swap\")": {},
    "@plugin \"@tailwindcss/typography\"": {},
    "@plugin \"tw-animate-css\"": {},
    "@layer base": {
      "body": {
        "font-family": "Inter, sans-serif"
      }
    },
    "@utility content-auto": {
      "content-visibility": "auto"
    }
  }
}
```

## Add custom animations

Note: you need to define both `@keyframes` in css and `theme` in cssVars to use animations.

```json title="example-component.json" showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "custom-component",
  "type": "registry:component",
  "cssVars": {
    "theme": {
      "--animate-wiggle": "wiggle 1s ease-in-out infinite"
    }
  },
  "css": {
    "@keyframes wiggle": {
      "0%, 100%": {
        "transform": "rotate(-3deg)"
      },
      "50%": {
        "transform": "rotate(3deg)"
      }
    }
  }
}
```

## Add environment variables

You can add environment variables using the `envVars` field.

```json title="example-item.json" showLineNumbers {5-9}
{»
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "custom-item",
  "type": "registry:item",
  "envVars": {
    "NEXT_PUBLIC_APP_URL": "http://localhost:4000",
    "DATABASE_URL": "postgresql://postgres:postgres@localhost:5432/postgres",
    "OPENAI_API_KEY": ""
  }
}
```

Environment variables are added to the `.env.local` or `.env` file. Existing variables are not overwritten.

<Callout>

**IMPORTANT:** Use `envVars` to add development or example variables. Do NOT use it to add production variables.

</Callout>

## Universal Items

As of `2.9.0`, you can create universal items that can be installed without framework detection or components.json.

To make an item universal i.e framework agnostic, all the files in the item must have an explicit target.

Here's an example of a registry item that installs custom Cursor rules for _python_:

```json title=".cursor/rules/custom-python.mdc" showLineNumbers {9}
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "python-rules",
  "type": "registry:item",
  "files": [
    {
      "path": "/path/to/your/registry/default/custom-python.mdc",
      "type": "registry:file",
      "target": "~/.cursor/rules/custom-python.mdc",
      "content": "..."
    }
  ]
}
```

Here's another example for installation custom ESLint config:

```json title=".eslintrc.json" showLineNumbers {9}
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "my-eslint-config",
  "type": "registry:item",
  "files": [
    {
      "path": "/path/to/your/registry/default/custom-eslint.json",
      "type": "registry:file",
      "target": "~/.eslintrc.json",
      "content": "..."
    }
  ]
}
```

You can also have a universal item that installs multiple files:

```json title="my-custom-starter-template.json" showLineNumbers {9}
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "my-custom-start-template",
  "type": "registry:item",
  "dependencies": ["better-auth"],
  "files": [
    {
      "path": "/path/to/file-01.json",
      "type": "registry:file",
      "target": "~/file-01.json",
      "content": "..."
    },
    {
      "path": "/path/to/file-02.vue",
      "type": "registry:file",
      "target": "~/pages/file-02.vue",
      "content": "..."
    }
  ]
}
```
